ratentea nan i, iaia Application filed September 9, 1908. Serial No. l52,525.

Be it lknown that I, JoHANNEs CnnisriAAN LEBUINUs vANnnn LAnon, a subjectof the Queen of the Netherlands, residin at .Deventer, in the Kingdom of-th Net ierlands, have invented a new and usefu and Thickening Apparatus, of Which the following isja specification.

f There are `known apparatus for de'color-` 'ing, bleaching and thickening oils, in Which i the oil contained in a tated hymeans of ladles rotating in op io-` and is subjected to the action paratus present the .conopressed.` air through the oil in the-apparatus is com-` paratively shdrt, so that. the coinpressed air i can act uponethe oil only heated boiler is agisite directions of coi-npressed air. Such a the defect, that the path o' tively short "period Therefore a" larger quantity of compressed air is required'for accomplishing the Work, Which means an inpower, so that the .useful eifectof the apparatusis thereby reduced. In such apparatus the lcompresed air can not be sutfiucientl-y' distributed over, the Whole mass of the oil, as neither the agitat-or n'or the yintroduction=of the compresscd air in several jets prevent the articles of air from collecting together to (irm, larger hobbies, Whereby both their action and theirsurfacs are'reduced... i f i -i i "My invention relates to improvements in such apparatus, ayoided, as 'the compressed air is obliged to describe a inuchdonger path through the oil and to conieinto intimate contact With every parti'cle of oil and to act upon the oilfor a longer period, before it is permitted to escape from the apparatus.

I Will now roceed to describe my invento the accompanying drai'ving, in Whichi Flgure 1 isa vertical cross section throu 'h jan improved apparatus on the line B-B in Fig. 2, and Flg. 2 is a horizontal section through the sagne on the line A-L-A in Fig. l.

Similar `characters of reference' refer th similar parts in both views. i If The oil boiler 1 has the usne-l cjflindrical Wherehy the knownlheating cha'rnher 2 is formel. L'fhe hoiler 1v is closed and -is interna? divided by several snperposedpar /into compartments li, 4, li',

Which conimunicate With one,I another l i l' Oil Decol- ,A posed in radal Whereby" the said defect is` A and to passto the perlphery and 6, 6 in the center around the A agitator shaft 7, these openings 5, 6 alternating With each other. Some of the pan 'titions, viz. 3', 3',are fastened on the agitatorehaft 7 and are therefore obliged to partake'in the rotation ofv the' latter, 'While the other partitions 3,63 are stationary and are fastened on the inside of the boiler 1. The agitator shaft 7 is journaled in a foot step 10 of any known construction and in the 'cover of ```the boiler 1 and is be set in rotation from Without by means .of hevel wheels 8 and 9. In' the ments a of the lioiler 1 ladies 11., 11' are displanes (see Fig. 42), of Which ithevladles ll are fastened on the bottom 32 'of the boi1er=and on the upper and lower sides"ofgtheseveral stationary partitions `While the ladles ll' are'fastened on the lower or upper-sides of the rotary partitions 3', the stationari] ladies With' therotary ladies Il'A leaving narrow Spaces 12, 12 `between. them -and along the opposite partition or Wall 3 or 3' or 3* at the .moment that allthe ladies are in the radial planes as is clearly shown at lig.v 1.v A chamher of any known construction surrounds the foot step 10 and compartarranged to coininunicates With the lowerinost 'compart-'- `nient 4 by a central annular opening 6'. The coinpressed air can besupplied from any source through a tube 14 to the Ghana-` her 1'5, after the stop valve 13 has heen o ened, and the Wasted air'can hadisc rged Vfromdthe top of the'boiler through a tube 17, after a stop valve r16 has been opened.

lt Will be seen that the compressed air' entering the lowermost compartmentV 4 through the central opening 6' in the direction of the arrows is compelled to spread periphery,"before lt can enter the next following compartment 4 through the annular opening 5, whereupon it is compelled to pass inwardly toward the zshaft 7 before Ait can .enter the nextjfollow- `ing `compartrnent 4 through the central' "opening 6 and spread therein to'the eri herx, and so on, nntilit is permitte to escaflpe'through the'tdhe 17. During the rotation of the agitator shaft ladies 11', ll' passing through; the spaces between the stationary ladies 11, 11 Will strongly agitate the oil'fand produce Whirls enverywhere, the oil`beihg pushed through.

'i' the .rotatory the said Spaces and throw'n in all directions on the rotatory ladles moving away from the respective stationary ladles and approaching the lines of the following stationary ladles,

5 so that the compressed air is necessarily mixed intimately and thoroughly With the oil for acting upon the same. The fine particles of air distributed among the particles of oil will be prevented fromcollectingand i 17510 forming larger bubbles, While the different i particles of oil and .compressed air Will constant'ly rub against `one ,another under a 'great pressure. It is obvious, that in opposition to the old appara'tus, in Which the eompressed air Was permitted to at once pass iipWard from the bottom to the top of the boiler, in the improved apparatus the path of the severalparticles of compressed air through the mass of oil is extremely drawn out and the period during Which each particle of compressed air is permitted to act upon the oil isV in pro- 3o 32 arer shown as plain, but they may be cor- 1Trugated, conical, funnel-like, convex or concave or otherwise curved.

I claim: '4 1. In an 011 treating apparatus of the class --B described, the 'combination With a vertical boiler circular in'section and adapted to contain oil, of a vertical shaftmounted in the A center'line of said hoiler to turn and'adapted to be driven from Without, rotary parti- 40 tions fastened on said vertical shaft and i leaving side 'of said boiler, stationary partitions in said boiler alternating With said rotary pari ti'tionsand leaving small central openings f around said vertical shaft, so that the hoiler is divided into superposed compartments,

each a narrow space along the inslationary ladlcs in the several eompartments and fastenedon said hoiler and said stationary partilimis resperiiwly While leaving narrow spaces at said rolaiory partitions, ladles faslened on said rotaiory parlil tions and adapted to pass snun'ly between said slationary ladies and said slationary partitions Or the bottom of said boiler for agitating the oil, means for supplying compressed air to the bottom of said hoiler. and means for discharging the \vasted air from the top of said boilcr.

2. In an oil treat ing;` apparalns of the class described, the coinbinution With a. vertical hoiler circular in section and adapted to contain oil, of a vcrtiml shaft mounled in the center line of said boiler 1o turn :indadapted to be driven from Without, rotat'ory partitions fastened on said vertical shaft and leaving each a narrowtsecc along the inside of said boiler. siationary partitions insaid boiler alternating with said rotal'ory partitions and i eaving` small central openings around said ve.`` ical shaft. that the boiler is divided into snperposed cm'npartments, stationary ladies in the several compartmcnl's and fastened on said hoiler and said stationary partitions respcctirely While leaving narrow Spaces at said roiatory partitions, agitating ladies faslcnod on said rotatory partitions and adapl'eil to pr snngly between said stationary ladlcs and s id stationar'ff pa "titions or the bottom of said boiler for agitating the oil.l all of said stationary ladles and said auitating ladles hei ing for a certain position of said vertical shaft in, the same. radial planes, means for supplying compressed :nr lo the bottom of said boiler, and mcans'ior disehargnig the \vasted air from the top of said boiler.
